daily inspections were the rule ; in other colonies, the burlaps 

 were examined every second or third day. In residential 

 districts, where small colonies were widely scattered, bicy- 

 cle gangs were organized among the employees, and by this 

 system the colonies received constant and thorough atten- 

 tion. As the insects approached the pupal stage, infested 

 walls were burned out with oil, and areas of brush land in 

 which the larvae had appeared were also burned with the 

 oil spray. 



The beginning of August marked the termination of the 

 larval and pupal seasons. The burlaps were given a final 

 inspection, and all places where the treatment could be used 

 with advantage were thoroughly burned with oil spray. 

 The burlap season having passed, the field work was dis- 

 continued from August 18 to September 5. The work of 

 removing the burlap was begun early in September, a 

 search for eggs being made at the same time. As the 

 process of hunting for egg-clusters is necessarily a slow 

 one, the removal of the burlaps was not completed until 

 near the end of the month. In woodland colonies all 

 serviceable burlaps were left on the trees for the next year. 

 The fall inspection was prosecuted rapidly in the outer 

 towns. In the inner towns, egg killing, burning of brush 

 and tinning of cavities in infested trees received the atten- 

 tion of a large number of employees. The numbers of 

 the force were gradually reduced by suspension and dis- 

 charge, the most experienced men being retained for the 

 fall inspection. 



In October the work of scouting and egg destruction was 

 continued. Towns which had not been examined for two 

 or three years were given a thorough search, and all find- 

 ings of the moth promptly stamped out. Considerable 

 attention was given to tinning cavities in infested fruit and 

 shade trees, thereby destroying many hiding-places of the 

 moth. Infested walls noted during the fell inspection were 

 sprayed with oil in order to destroy the egg-clusters, — a 

 method which is both cheap and efiective. A large amount 

 of eflbrt was directed towards clearing up the newly found 

 colonies in Newton and Georgetown. These localities were 

 scouted by trained men, Avho were followed by gangs of
